Advanced energy management control for energy storage systems

An energy management controller based on multiple charge/discharge profiles is proposed and analysed for an energy storage system. Each profile is designed to use the available energy more aggressively in different power regions, including the low- or the high-power regions, or both regions to minimise the rate-of-change of the power source output. The performance of the energy storage system with the profiles is examined by simulation when connected to an aircraft 540-V DC bus with a fault-tolerant starter/generator and high-power pulsed loads.
